I had to pick the last option since my nick here is neither
perfect for me nor something mistakenly chosen.

Whenever I join a new group, I pick a nick based upon how I'm
feeling that day. That can be a new nick, or one of the ones
I've already gone by in the last 9 years. That becomes my
nick for all related activities, although I'll often have
other active nicks at the same time for other groups.

At the time I started using Perl I hadn't used kudra for
a while--I'd last used it as a testing character in a mud.
Now it's become the nick I'm most associated with.
